I am using Vodafone sim around more than three years till now. But I have never faced total network breakdown for the whole day as we face with BSNL.Some times the tower gets down but that is for 10min. to 15min. only.
The internet specificaly Vodafone 2G is the best network compare to any other network in India. Even I run Youtube video with 2G very smoothly.
The charges are also good in the whole telicom industries except Tata Docomo(India’s slowest network).
Example of some of the offers by Vodafone-Full taktime 10, 24, 70, 120etc.
Internet-1GB with 58.
Overall Vodafone is best budget network in India right now.
